It is used in large-signal power-amplifier, video-amplifier, oscil- @ic lator, and mixer circuits over a wide temperature range. This type can also be used in switching service in circuits requiring transistors having high voltage, current, and dissipation values. JEDEC No. TO-12 package; outline 11, Outlines Section. This type is identical with type 2N1493 except for the following items: MAXIMUM RATINGS COLLECTOR-TO-BASE VOLTAGE (with emitter open)..............-. oe 60 max volts COLLECTOR-TO-EMITTER, VOLTAGE (with emitter-to-base volts = 0.5). . 60 max volts EMITTER-TO-BASH VOLTAGE (with collector open).........0. 0. cee eenee 2 maz volta CHARACTERISTICS Collector-to-Base Breakdown Voltage (with collector ma = 0.1 and emitter current = )... 0.0 cc ce eee nent eneees 60 min volts In Common-Base Circuit Small-Signal Forward-Current-Transfer-Ratio Cutoff Frequency (with collector-to-base volts = 30 and collector ma = 15)............ 275 Me In Common-Emitter Circuit Power Gain at 70 Me (wita collector-to-base volts = 30, emitter ma = 15, and power output = 100 mw).........-...eceee 15 db TRANSISTOR Silicon n-p-n type used in a wide 2 NI 49 3 variety of high-frequency and vhf ap- plications in industrial and military equipment.
